49ers snap count vs. Seahawks: Leon McFadden, Alfonso Smith, Nick Moody benefit from injuries

The San Francisco 49ers dealt with numerous injuries leading up to and during Sunday's loss to the Seattle Seahawks, and it opened the door for quite a few reserves to get significant playing time. We've got the full snap count below, and you can view the full game book HERE.

The 49ers entered the game without cornerbacks Tramaine Brock and Chris Culliver. They promoted Marcus Cromartie from the practice squad on Saturday, and he managed a few snaps. Leon McFadden was the primary beneficiary, as Dontae Johnson took over the starting role, and McFadden took over nickel duties. Johnson finished the game with a 1.1 overall grade, and 0.8 pass coverage grade from Pro Football Focus. McFadden finished with a 0.8 and 1.0 in those areas. The 49ers coverage had some question marks at times, but for the most part did some fairly solid work on Sunday.

Frank Gore and Carlos Hyde both left the game with injuries. Gore suffered a concussion, and Hyde suffered a back injury. This resulted in Alfonso Smith finishing the game with 13 snaps. He even got hurt at one point, but stayed in the game. His injury came on the play before Bruce Miller was stuffed on 4th and 1. You could see Smith was shaken up, so it became pretty obvious Miller would get a second fullback handoff.

Tank Carradine finished the game with 19 snaps, and managed a pair of sacks on back-to-back plays. He finished the game with a 1.4 overall grade, and 0.7 in the pass rush. He has gotten limited work, but seems to be making good use of it. The 49ers defensive line faces a significant question about the future of Justin Smith, and if he departs, Tank and Quinton Dial will both get significant opportunities at the 3-4 defensive end role.

The other notable injury on the day was Chris Borland's ankle issue. He was unable to finish the game, which left the 49ers with Nick Moody next to Michael Wilhoite. Additionally, Wilhoite got banged up at one point on a special teams play. The 49ers ended up playing ten snaps of a 3-3-5 formation. They had some success in the first half with Borland still in the game, but when Borland left, the run defense took a noticeable step back.
