Sermon signed with Pittsburgh's practice squad Wednesday.

Sermon and Lew Nichols have been added to the practice squad as organizational depth behind rostered running backs Jaylen Warren, Kaleb Johnson and Kenneth Gainwell. Sermon has suited up for 42 regular-season NFL games, including all 17 with the Colts last season.

Nichols signed with Pittsburgh's practice squad Wednesday.

Nichols went unclaimed on waivers, opening the door for him to remain in the Steelers organization as a depth option. He'll be joined on the practice squad by Trey Sermon while Jaylen Warren, Kaleb Johnson and Kenneth Gainwell begin the season on the 53-man roster.

Estime is in line to sign with the Eagles' practice squad, Parker Gabriel of The Denver Post reports.

Estime was embedded in a battle for a roster spot in a crowded Broncos backfield this summer and lost out to J.K. Dobbins, RJ Harvey, Jaleel McLaughlin and Tyler Badie. After getting cut Tuesday, Estime cleared waivers one day later and quickly found a new home. He'll now be a depth option in the event Saquon Barkley, Will Shipley or AJ Dillon needs to miss time for any reason.

Williams signed with Cleveland's practice squad Wednesday.

Williams and Ahmani Marshall will provide organizational depth at running back for the Browns. While Cleveland's depth chart at the position is uncertain, the Browns gained one more mouth to feed Wednesday when they claimed Raheim Sanders on waivers, adding him to the roster alongside Jerome Ford and Dylan Sampson, as well as unsigned rookie Quinshon Judkins.

Marshall signed with Cleveland's practice squad Wednesday.

Marshall's path to a promotion to the roster got more complicated when the Browns added running back Raheim Sanders via waivers Wednesday, giving them three available running backs in Sanders, Jerome Ford and Dylan Sampson, as well as unsigned rookie Quinshon Judkins. Like Judkins, Sampson and Sanders, Marshall is a rookie, having signed with Cleveland in April out of Appalachian State.

Buffalo signed Gore to its practice squad Wednesday, Alec White of the team's official site reports.

Gore was waived by the Bills on cutdown day Tuesday, but he's remaining with the organization on the practice squad. The 23-year-old will look to earn a chance on the active roster at some point during the season for what would be his NFL regular-season debut.

Milton signed with Cincinnati's practice squad Wednesday.

Milton and Gary Brightwell both joined the Bengals' practice squad after going unclaimed on waivers following final cuts. They will provide organizational backfield depth behind Chase Brown, Samaje Perine and Tahj Brooks, who all made the 53-man roster.

Brightwell signed with Cincinnati's practice squad Wednesday.

Brightwell remains with the Bengals as organizational depth after passing through waivers unclaimed. He or fellow practice squad running back Kendall Milton would presumably be next in line for opportunities should injuries befall any of the three running backs on Cincinnati's 53-man roster.

Texans general manager Nick Caserio declined to answer in the affirmative when asked Wednesday whether Mixon (foot/ankle) will suit up this season, DJ Bien-Aime of ESPN reports.

Mixon is officially out the first four games of the year after having been placed on the Reserve/Non-Football Injury list Tuesday, but when prompted Wednesday for more clarity about a timetable for his potential return to the field, all Caserio said was that the team will "take it one day at a time," and that players on IR or the NFI lists will be evaluated "after four weeks and see where they are in their progression and then make a determination." Mixon has been sidelined throughout spring activities, training camp and the preseason, leaving Nick Chubb, Dameon Pierce, Woody Marks and Dare Ogunbowale as Houston's top backfield options to open the regular season.

Steele signed with Kansas City's practice squad Wednesday, Matt Derrick of ChiefsDigest.com reports.

Steele failed to make the 53-man roster out of training camp but went unclaimed on waivers, so he'll stick with the Chiefs organization. He can contribute as either a running back or fullback in the backfield, but Steele isn't guaranteed to be the next man up if injuries strike, as Clyde Edwards-Helaire is also signing with Kansas City's practice squad.
