• Kittle remains on injured reserve with a Week 1 hamstring strain and is not expected to be activated for the Buccaneers game, according to Kyle Shanahan.
• Week 7 against the Falcons is viewed as the more realistic target for his return, with practice windows for Kittle and Brandon Aiyuk set to remain closed through Monday.
• Safety Malik Mustapha will have his 21-day practice window opened Monday as he works back from an ACL injury sustained last season.
• In other updates, Kalia Davis is undergoing surgery for a broken hand, Yetur Gross-Matos will miss a little time with a hamstring strain, Alfred Collins has a knee sprain, and Upton Stout is day-to-day with an ankle sprain.
• Tight ends Jake Tonges and Luke Farrell have covered in Kittle’s absence as the 49ers improved to 4-1 with an overtime win over the Rams.
