SANTA CLARA -- 49ers wide receiver Pierre Garçon will undergo a season-ending procedure on his knee on Tuesday.
Garçon, 32, missed the past four games with a knee condition and will go on injured reserve this week, coach Kyle Shanahan said Monday.
The veteran wideout appeared in eight games this season and caught 24 passes for 286 yards and one touchdown, but Garçon’s future with the 49ers is in question. He is scheduled to earn $6 million in salary and bonuses next season.
The 49ers have three wide receivers on the practice squad who are candidates to be promoted for the final three games: Victor Bolden Jr., Max McCaffrey and Steven Dunbar.

In other injury news, defensive end Cassius Marsh reported to the team facility with concussion symptoms on Monday and was placed in the NFL’s return-to-play protocol.
Cornerbacks Ahkello Witherspoon (ankle) and Tarvarius Moore (shoulder) are day-to-day. Running back Matt Breida (ankle), safety Jaquiski Tartt (shoulder), cornerback K’Waun Williams (knee), and linebackers Mark Nzeocha (groin) and Malcolm Smith (Achilles), will be re-checked on Wednesday.
Rookie defensive lineman Kentavius Street, a fourth-round pick who tore his ACL in the pre-draft process, might practice this week, Shanahan said. Street remains on the non-football injury list. He will not play this season, but the 49ers can get him on the practice field for the final three weeks.
