Texans CB Brandon Harris is going through concussion protocol after getting knocked out in OTAs this week.

"We're putting him through the protocol that you would do during the regular season," coach Gary Kubiak said. "A guy gets dinged like that, gets knocked out like he did, we'll put him through the total protocol. You probably won't see him for a good week as he goes through the process." Harris collided with first-round WR DeAndre Hopkins earlier in the week. He might sit until minicamp.

Texans signed third-round DE/OLB Sam Montgomery to a four-year contract.

Montgomery (6-foot-3, 262) is a questionable fit at outside linebacker in the Texans' 3-4 defense, but that's where the team currently plans to play him. He and fourth-rounder Trevardo Williams could be competing for the starting job opposite Whitney Mercilus, and Williams reportedly has looked better so far.

49ers signed second-round DE/OLB Tank Carradine to a four-year contract.

Carradine (6-foot-4, 276) tore his ACL in November, and the team "hopes" he'll be ready for training camp. When healthy, he's a powerful pass rusher with a relentless motor. The Niners are just collecting talented edge rushers.
