Gore is going to be out for a length of time with this strained ligament. He will certainly miss Games 4 & 5 (or more), and is likely to be less than 100% for the remainder of the season. Ligaments don't "heal" quickly.
So, the Niners need another RB, probably before Wednesday's practice, so that player can get a full week of practice and be prepared to contribute vs the Rams in Game 4, if needed. Sheets may well be the best alternative. He knows the plays and has taken reps with the other Niner players.
But whom do you cut to make room for Sheets on the 53-man roster? I'll nominate Spurlock as the guy to be cut, and give Sheets additional practice reps on ST, as a possible KR back-up for Rossum (with Spurlock gone). Install Robinson as the Taser guy (with Spurlock gone). Jason Hill remains available on the 53-man roster for game-day activation, if one of the first 3 WR (Bruce, Morgan or Battle) become injured (with Spurlock gone).
