Titans QB Mariota (elbow) making progress

Houston Texans: Veteran cornerback Shareece Wright was signed after the loss of starting cornerback Kevin Johnson (concussion) for at least eight weeks after the Texans placed him on injured reserve. Wright is in his eighth NFL season, and coach Bill O'Brien sees him as a good fit in the secondary. "Size, experience, he's got a lot of snaps in the league, a good guy," O'Brien said. "All reports on him being a real good teammate. Glad we were able to get him." When it came to losing offensive tackle Seantrel Henderson with a season-ending ankle injury, the Texans stayed in-house and promoted Roderick Johnson from the practice squad to be a backup.

Indianapolis Colts: Left tackle Anthony Castonzo is progressing well from the hamstring injury that caused him to miss the opener against the Cincinnati Bengals and is on track to play Sunday against the Washington Redskins. Castonzo missed the entire preseason because of the ailment, so being back on the football field is therapeutic for his mindset. "Feeling good," Castonzo said. "I'm excited to have a full week of practice and get out there and play." Running back Marlon Mack (hamstring) also missed the opener, and his status is less solid. Rookie Jordan Wilkins (40 yards on 14 carries) is expected to get most of the practice repetitions and likely will make his second consecutive start.

Jacksonville Jaguars: Running back Leonard Fournette will test his injured hamstring Friday, according to coach Doug Marrone, and possibly could play in Sunday's game against the New England Patriots even if he misses the week's workouts. "He's done a good job. He has worked really hard," Marrone said. "I would be comfortable with him (playing). If it was a rookie, maybe ... depending on the situation or position or things of that nature I might not be as comfortable." Marrone will not be coy about Fournette's status to toy with the Patriots. "If guys are ready to play, they play, and we'll get him out there," Marrone said.

Tennessee Titans: Quarterback Marcus Mariota participated in practice Wednesday, and his throwing elbow is no longer prompting concerns. "I am feeling pretty good," Mariota said after the practice. "I am kind of taking it one day at a time, but I was able to go through practice today and felt pretty good. For me, I just went through practice and felt it went fine." Titans coach Mike Vrabel liked what he witnessed and is counting on his signal-caller being ready for Sunday's game against the Texans. "He had some rest Monday and Tuesday, so he was able to get through and do everything and really looked OK," Vrabel said. "I would say barring any setbacks that Marcus is going to be good to go on Sunday."
