49ers rookie wideout Trent Taylor may not finish his first NFL season. Head coach Kyle Shanahan revealed earlier today that the receiver broke a rib on a non-contact play, although the team is hoping he’ll see the field again this year (via Matt Barrows of The Sacramento Bee on Twitter). Meanwhile, the team is preparing to place three players on the injured reserve (via Eric Branch of the San Francisco Chronicle on Twitter), including safety Jaquiski Tartt, tight end Cole Hikutini and offensive tackle Garry Gilliam. We heard yesterday that Tartt was likely done for the season.

Taylor, who was selected in the fifth round of this past year’s draft, has gradually climbed the 49ers depth chart throughout the season. The rookie had appeared in all nine games, hauling in 24 receptions for 204 yards and one touchdown. The Louisiana Tech product had also returned 17 punts for 167 yards. The team signed wideout Louis Murphy earlier today for some reinforcement at the position, as they were previously rostering only four healthy wideouts in Marquise Goodwin, Aldrick Robinson, Kendrick Bourne, and Victor Bolden.
