HOUSTON (AP) Texans quarterback C.J. Stroud returned to practice on a limited basis Wednesday, but Matthew Boyd Jersey the star rookie remains in the concu sion protocol and his status for Sundays game against Tenne see is uncertain.He's in stage four of the concu sion protocol, still has one more phase, coach DeMeco Ryans said. Stroud has mi sed the past two games after sustaining a concu sion in a Dec. 10 lo s to the Jets when his head bounced off the turf after taking a hit with about 6 minutes left in the fourth quarter.Its encouraging to have C.J. back out at practice today, its encouraging to see him, Ryans said. I think it just lifts everybodys spirits to see him back doing well. He's still progre sing in the right direction so (I'm) happy about that.ADVERTISEMENT The Texans (8-7) remain in contention for both the AFC South title and a wild-card playoff spot, but a lo s Sunday would drop their chances to reach the postseason for the first time since 2019 to just 13%. Veteran Case Keenum has started the past two games with Stroud out. He threw for 229 yards and a touchdown to help Houston to a 19-16 overtime win against the Titans two weeks ago but struggled in a lo s to Cleveland last week, throwing for just 62 yards and to sing two interceptions.Davis Mills, the teams starter for most of the past two seasons, played a couple of snaps early against the Browns but took over for good after Keenums second interception late in the third quarter. He threw for 149 yards and two touchdowns late but it wasnt Nick Castellanos Jersey nearly enough as the Texans lost 36-22.If Stroud can return Sunday it will be a big boost to the Texans. The second overall pick is the biggest reason for Houstons improvement this season and he has thrown for 3,631 yards and 20 touchdowns with just five interceptions.___AP NFL:
