ENGLEWOOD — Broncos wide receiver Marvin Mims left practice Wednesday to be evaluated for a groin injury.

Denver is not “overly concerned” about his health status, coach Sean Payton told pool reporter Jeff Legwold. Payton did not address the full media group following practice at Broncos Park.

Mims is a key piece of Denver’s receiving corps and special teams.

He was selected to the Pro Bowl in each of his first two NFL seasons as a return specialist. Mims was also named first-team All-Pro last year as a punt returner. Offensively, he’s logged 61 catches for 880 yards and seven touchdowns over two seasons in Denver.

Longest week

The Broncos are currently stuck in limbo.

Denver has one more practice Thursday to focus on themselves before game preparation begins next week. The Broncos host the Titans on Sept. 7 inside Empower Field at Mile High.

“I think this week is the longest week of the year just because guys are ready to roll,” cornerback Riley Moss said Wednesday. “The biggest thing about this week is making sure you don’t take any steps back (and) making sure you’re still approaching practice how you should, because it is kind of a trap week. You can take it as we don’t have a game this week, but we’re … attacking it and we’re going to be ready to roll next week.”

Moss is confident entering his second year as a full-time starter opposite Pat Surtain in the secondary. He added strength and weight this offseason to better defend physical wide receivers at the point of attack. But Moss isn’t getting comfortable, either.

“Something that I learned in college, after starting my freshman year, was (that) I kind of got comfortable,” Moss said. “I got the spot, and then I ended up having a couple of bad games and then the spot’s taken from (me). So, I think the biggest thing is not getting comfortable. I’m glad I went through that in college. … You have to continue to attack every day and not get comfortable.”

Number change

Quarterback Bo Nix began training camp lauding the improvement of wide receiver Troy Franklin.

That included his jersey number change from No. 16 to No. 11 — the digits that Franklin wore as college teammates with Nix at Oregon.

“I think the transition to 11 from 16 is good for him. It looks better,” Nix said July 26. “I think he’s just more natural and he feels comfortable.”

On Wednesday, after practice at Broncos Park, Franklin confirmed that one source of his confidence is from changing numbers.

“I’ve been in 11 my whole life,” Franklin said. “Sixteen was just a little different. It just didn’t fit me. But I’m glad to be back in 11, for sure.”

Franklin had a strong preseason performance. He scored two touchdowns against the Cardinals in the first half at home. Franklin is also playing multiple receiver positions.

“I think it’s just that my confidence is up there,” Franklin said. “I had a really good offseason. … I kind of just wanted to translate that onto the field, in my practices (and) training camp. I was trying to be consistent.”
