Seahawks running back Christine Michael tweaked his hamstring in practice Tuesday and won't play in Thursday's preseason finale, reports 710 ESPN Radio. Coach Pete Carroll said Michael "pulled up a little bit" when he got hurt.

The Dolphins waived receivers Armon Binns and Ryan Spadola, tight end Brett Brackett, cornerback Steven Clarke, defensive end Rakim Cox, defensive tackle Cory Grissom and center Tyler Larsen. Miami also put defensive tackle A.J. Francis, running back Mike Gillislee and tight end Arthur Lynch on injured reserve, ending their seasons.

Dolphins running back Daniel Thomas has not played in the first three preseason games and knows he's in danger of getting cut, reports the Palm Beach Post. Thomas, who will play Thursday against the Rams, said he feels he has a lot to prove.

"I haven't been out there in a while," he said. "I just want to show coaches that my hamstring is good. I feel good and I'm ready to play good."

Behind Lamar Miller and Knowshon Moreno at running back, the Dolphins have impressive undrafted rookie Damien Williams. To make the team, Thomas might need Miami to keep four running backs, the paper said.

Ravens running back Bernard Pierce missed Tuesday's practice as he continues to recover from a concussion, reports ESPN.com.

Packers running back DuJuan Harris played so well Friday against the Raiders that he's now pushing James Starks for the No. 2 spot on the depth chart, reports the Milwaukee Journal-Sentinel. Harris rushed 12 times for 56 yards and caught passes of 31 and 11 yards.

"That's a question that has yet to be determined," running backs coach Sam Gash said of the pecking order behind Eddie Lacy. "We're still going through the process."

Added offensive coordinator Tom Clements: "Obviously, Eddie's our top runner. After that, we're going to mix guys in there and see where it goes."

The 49ers made several moves to trim the roster to 75 players Monday.

The team waived quarterback McLeod Bethel-Thompson, safety D.J. Campbell, tight end Kevin Greene, running back Jewel Hampton, punt Colton Schmidt, linebacker Kion Wilson and wide receiver Devon Wylie, while also releasing wide receiver David Reed.

The team placed running back Marcus Lattimore, fullback Trey Millard, cornerback Keith Reaser and guard Brandon Thomas on the Reserve/Non-Football Injury List and linebacker NaVorro Bowman, tight end Garrett Celek and defensive tackle Kaleb Ramsey were placed on the Reserve/Physically Unable to Perform List. Linebacker Blake Costanzo was released from the Injured Reserve list.

Rams running back Zac Stacy did not start the third preseason game, but he remains atop the depth chart, according to ESPN.com. Benny Cunningham, who got the start, is the No. 2 back ahead of rookie Tre Mason.

The Chargers waived or released these players: running back Kerwynn Williams, offensive tackle Nick Becton, fullback Zach Boren, tight ends Ryan Otten and Jake Byrne, receivers Micah Hatfield and Brelan Chancellor, linebacker Adrian Hamilton, guard Darryl Johnson, cornerback Lowell Rose and punter Chase Tenpenny.

Ravens running back Bernard Pierce has a mild concussion, coach John Harbaugh told ESPN.com. Pierce did not practice Monday but is expected to be ready for the regular-season opener.

Trent Richardson is averaging 2.6 yards per carry in the preseason, and Ahmad Bradshaw made his preseason debut Saturday with three carries for 2 yards. Would the Colts turn to Dan Herron?

Herron has run for 104 yards on 18 preseason carries (5.7 ypc), including a 43-yard jaunt Saturday against the Saints. Most of those yards have come against backups, but coach Chuck Pagano said he's not discounting Herron.

"I don't look at it that way," Pagano told ESPN.com. "I just know 'Boom' has had a really good camp and a good preseason. He's made some nice runs. It's comforting knowing that you have a guy that not only excels on special teams, but you've got another guy in the backfield that can run and get yards for you when you need them."

A third-year back out of Ohio State, Herron entered camp as a long shot to make the roster. Now he's third on the depth chart and rising fast. "It's a great opportunity right now for me," said Herron, who also returns kickoffs. "I come here every day like it's my first day and the coaches know nothing about me. I try to work as hard as I can and just try to showcase what I can."
