Andy Reid

Wide receiver Justin Jenkins, who was injured on the opening kickoff Saturday night against Baltimore, is finished for the season after tearing his ACL.

Reid said that Carlos Perez will take over the No. 5 spot in the receiver rotation. Perez has "had a good camp" according to Reid. In the two preseason games, Perez has a team-high seven catches for 62 yards.

The other key injury update involved cornerback Dexter Wynn. After taking the opening punt of the game 74 yards for a touchdown, Wynn was injured on a defensive play in the second quarter. Wynn suffered a high ankle sprain and will not play this Friday against Cincinnati. It "would be a stretch" for Wynn to make the season opener against Atlanta.

RB Reno Mahe takes over punt return duties for Dexter Wynn

"I felt comfortable back there doing it (last year)," Mahe said. "I have to work a lot more on it. I did a horrible job of it last year as in my average per returns. I have to get better to help the team. I don't know what happened. I just didn't do my job."

Mahe averaged 5.7 yards per return on 19 attempts in 2004. Reid said that Mahe is a secure catcher, which is "the first thing you look at." But Mahe said that he wants to be more than that.

"With Coach (John) Harbaugh and how great he coaches up these guys, you gotta do more than that (catching the ball)," Mahe said. "You have to do your part in making plays.

"Like Deion Sanders says, there's always a seam. You saw Dex last game, he hit it perfect."

Reid is comfortable with Mahe as the main punt returner for now.

"I think he'll be fine," Reid said. "The first thing you look at is securing the football. Then, (you look at) pounding it up in there and how many yards you can get after the catch. He is a secure catcher and he can be productive back there."

Reid said that cornerback Lito Sheppard and running back Brian Westbrook will backup Mahe as the punt returners. Reid is not completely against the thought of putting a starter in to return punts, but he would like to avoid it if possible.

"I'm not saying that we won't do that," Reid said. "Right now, I'd rather not go that route. But it can happen."

Injury Report

Running back Correll Buckhalter is meeting with Dr. James Andrews today. An update on his status could come later on Monday.

Defensive end Trent Cole (sternum), defensive end Jamaal Green (foot sprain), center Jamaal Jackson (tricep tear), linebacker Mike Labinjo (shoulder contusion) and defensive tackle Keyonta Marshall (PCL sprain) will all miss Monday's practice.

Cornerback Matt Ware will return to the field after being sidelined with knee soreness and a toe injury. He will replace Wynn on the field.

Herrion's Death Puts Things In Focus

Reid commented on the death of San Francisco 49ers offensive lineman Thomas Herrion. The 23-year old died Saturday night in Denver following the team's preseason game against the Broncos.

"That's a sad deal. He was a great kid," Reid said. "To have something like that happen to him and his family is devastating. You don't want it to happen to your team. You try to take all of the precautionary measures, and I'm sure the 49ers did. Sometimes things happen. It's a shame."
