Kyle Shanahan is a young man with a sharp mind capable of recalling specific details about plays he called weeks, even years, in the past.
But the 49ers coach needed a cheat sheet on Monday to help him through his team's latest round of injuries. The list:
* He said tackle Garry Gilliam, tight end Cole Hikutini and safety Jaquiski Tartt would go on injured reserve. Gilliam and Hikutini suffered MCL sprains, Tartt broke his forearm. That gives the 49ers a league-leading 23 players who have gone on injured reserve this year. The team signed tight end Logan Paulsen, who has been on and off the roster all season, and veteran receiver Louis Murphy on Monday.
* Three rookies -- Receiver Trent Taylor, tight end George Kittle (ankle) and linebacker Elijah Lee (knee) -- won't play in the upcoming game against the Giants. Taylor broke a rib in the first half and didn't play the rest of the game. Shanahan said the hope is that he and the others are back after the team's Nov. 19 bye.

* Shanahan said Joe Staley (eye), Brandon Fusco (biceps), Dontae Johnson (shoulder), Solomon Thomas (knee), Kyle Juszczyk (neck), Aaron Lynch (calf) and D.J. Jones (knee) are possibilities to play but that most of them will be up in the air until game time.
Shanahan said Hikutini would have been an option to replace Taylor as the slot receiver. As it stands now the team will take a committee approach to that position. He also said that Kittle’s ankle injury -- it happened on San Francisco’s first offensive play -- was bad enough that team doctors checked him out for a broken leg.
Hikutini was hurt just a little later and then Juszczyk went down as well. So Kittle volunteered to go back onto the field.
“He allowed us to be functional,” Shanahan said. “And he earned a great deal of respect from me for doing what he did.”
