Jackson (hamstring/finger) will begin a rehab assignment with Triple-A Gwinnett on Wednesday, David O'Brien of The Athletic reports.

Jackson was on a rehab assignment earlier in the month while recovering from a left hamstring strain, but he suffered an injury to his pinkie finger that forced him to pause his activities. The catcher was transferred to the 60-day IL and isn't eligible to return until this weekend, but he'll resume his rehab assignment Wednesday and could be back with the major-league club in the near future.

Marlins manager Don Mattingly said Leon will catch for starting pitcher Jordan Holloway in Wednesday's game at Philadelphia, Jordan McPherson of the Miami Herald reports.

Leon will crack the starting nine for only the second time in 12 games. Jorge Alfaro is locked in as the Marlins' clear top catcher, and opportunities will likely remain few and far between for Leon while Alfaro is healthy.

Contreras isn't starting Wednesday's game against the Mets.

Contreras went 0-for-2 with a walk in Tuesday's loss, and he'll take a seat for the second time in the last three games. Kevan Smith will start behind the dish and bat eighth.

Perez will start at catcher and bat seventh Wednesday against the Rockies.

No. 1 backstop Jacob Stallings is getting the afternoon off after making three straight starts behind the dish, so Perez will check into the lineup for the 23rd time this season. Perez has delivered five extra-base hits in his limited opportunities in June, but he doesn't appear likely to move ahead of Stallings on the depth chart anytime soon.

Stallings is out of the lineup for Wednesday's game against the Rockies.

Stallings will head to the bench for the series finale after he logged starts at catcher in each of the past three contests while going a collective 2-for-10 with a walk and four strikeouts. Michael Perez will check in for Stallings behind the dish.

Diaz is out of the lineup for Wednesday's game against the Pirates, AT&T SportsNet Rocky Mountain reports.

After he was behind the plate for each of the Rockies' last three games, Diaz will cede catching duties to Dom Nunez in the series finale. With Diaz having homered in back-to-back games and recorded at least one hit in four straight contests, he appears to have solidified his spot atop the depth chart for the time being.

Diaz went 2-for-4 with a solo home run in an 8-0 victory over Pittsburgh on Tuesday.

The backstop crushed a 451-foot solo shot to center field in the fifth inning for his fourth homer of the season. Three of those long balls have come in his past eight games, including two in the past two days. The sudden power surge has helped Diaz get the majority of starts behind the dish of late, as fellow catcher Dom Nunez is hitting only .135 in June and hasn't homered since May 1.

Amaya (undisclosed) is on the 7-day injured list at Double-A Tennessee, Russell Dorsey of the Chicago Sun-Times reports.

The specifics of the issue remain unclear, though the young catcher has been on the shelf since early June. Amaya was hitting .215/.406/.304 with one homer, four doubles, 13 RBI, 11 runs and two stolen bases in 23 games for the Smokies prior to the injury.

McCann went 1-for-3 with a three-run home run and a walk Tuesday against Atlanta.

McCann provided the game-tying blast in the seventh inning, ending Charlie Morton's outing. It was McCann's seventh home run of the season and first since hitting four home runs in a seven-game span between May 29 and June 6. Overall, he has a .240/.300/.382 line with 16 runs and 28 RBI across 223 plate appearances.

Narvaez is not in the lineup for Tuesday's game against the Cubs.

Narvaez's off days typically come against lefties, but he'll get a rest here against righty Zach Davies. Manny Pina takes over behind the plate in his absence.
