Indianapolis Colts center Ryan Kelly expects to play in Saturday’s wild-card round game at Houston.
   Kelly practiced Wednesday after sitting out Sunday’s regular-season finale with a stinger. He also missed three games earlier this season with a sprained medical collateral ligament and now wears a brace to protect his left knee.
   Indy (10-6) did not allow a sack in the five games preceding Kelly’s first injury. The Colts allowed six sacks in the three games he missed, including two in a 24-21 victory at Houston in early December. They gave up another sack in last weekend’s playoff-clinching victory at Tennessee.
   Kelly was Indy’s first-round draft choice in 2016.
