49ers RB Hyde OK to play after taking big hit
In his second career start Sunday, 49ers running back Carlos Hyde suffered a quadriceps injury and exited to undergo a concussion test, which came back negative.
Hyde, 25, is fine to play Sunday at Arizona — he’s listed as probable — but the 235-pounder’s punishing running style could invite injuries.
Running back Reggie Bush (calf) is listed as doubtful for Sunday after he failed to practice during the week.
Bush worked on a side field at the start of practice and appeared to be running fine at half-speed.
Head coach Jim Tomsula said he didn’t want Bush to play if he wasn’t close to fully recovered.
Tight end Vance McDonald (knee) and wide receiver Bruce Ellington (ankle) are both questionable.
With Bush and Ellington sidelined at Pittsburgh, running back Mike Davis and wide receiver DeAndrew White made their NFL debuts.
Iupati is questionable after he had surgery on his left knee a few days after he injured his meniscus Aug. 18.
Inside linebacker NaVorro Bowman and Iupati were members of the 2010 draft class.
After a workout, Tomsula arrived for his midmorning news conference sweating so much that he brought a towel to the podium.
