The 49ers on Monday informed center Daniel Kilgore he will be placed on reserve/physically unable to perform, making him ineligible to play in the first six weeks of the regular season, a source said.
The move of placing Kilgore on reserve/PUP was one of 14 roster moves the 49ers have to make in order to reduce to their roster to the maximum of 75 players before the 1 p.m. deadline on Tuesday.

Kilgore opened last season as the starter, replacing Jonathan Goodwin, who started every game during the 49ers’ three consecutive playoff seasons. Kilgore played well before going down in Week 7 with a fractured left lower leg.
Kilgore underwent follow-up surgery in June and was placed on the PUP list at the beginning of training camp. He continues to wear an orthopedic boot on his foot.
Players who begin the season on reserve/PUP or reserve/non-football injury, are prevented from playing or practicing during the first six weeks of the regular season. After the sixth week through a day after Week 11, a player can return to practice. Then, the team has a three-week window during which time he can be activated to the 53-man roster.
