ENGLEWOOD, Colo. -- A daily review of the hot topics coming out of Denver Broncos training camp:
Backup quarterback Brock Osweiler will get a rather tidy training camp exam Saturday morning. The Broncos will hold their annual practice/summer scrimmage at Sports Authority Field at Mile High. And after some of their usual drills to open the workout they will send the No. 1 offense against the No. 2 defense for 12 plays of live tackling. And that means Osweiler and the No. 2 offense will try its hand against the No. 1 defense. "Brock is really going to have to be smart and moving the ball well against the 1s," Broncos offensive coordinator Adam Gase said. The combination to keep an eye on, at least if the last few days of practice are any indication, is Osweiler and undrafted rookie Bennie Fowler. The two have connected on several big plays, including touchdown throws Thursday and Friday. Fowler has worked with the second-team offense lately and if he's on the field Osweiler will look his way.
The running back rotation in the scrimmage will bear watching, especially how things go with the second and third units. Montee Ball figures to get most, or all, of the carries with the starters with Ronnie Hillman working as his backup right now. C.J. Anderson is expected to run with the second team while Juwan Thompson, Kapri Bibbs and Brennan Clay will likely mix and match with the third-team offense. Thompson, however, has taken second-team snaps in camp in short-yardage work.
Following Friday's practice, Broncos defensive coordinator Jack Del Rio had high praise for cornerback Chris Harris Jr.'s work in coming back from ACL surgery in February. Harris was cleared to return to practice this week, less than six months following his surgery. "I've been around guys that have rehabbed and come back from injury, but I don't know if I've ever seen a guy more determined every day with great energy attacking it the way he did," Del Rio said. "He's really stayed engaged mentally in the meetings. He's worked extremely hard and been very diligent, and it's gone well -- no setbacks or anything."
Linebacker Jamar Chaney, who started 23 games for the Philadelphia Eagles earlier in his career and had a three-interception season in 2011, had a leaping pick on a Zac Dysert pass in Friday's red-zone drills. Chaney leaped high to tip the ball up and then caught the tipped ball. Chaney, who has worked with the third-team defense the majority of the time, faces a tight battle at linebacker for the last few spots. The team kept seven linebackers in the cut to 53 players in 2011 and 2012 to go with six at the position last season.
The Broncos' practice/scrimmage at 11 a.m. at Sports Authority Field at Mile High will be their only practice Saturday.
Odds and ends: Defensive end Derek Wolfe, who left Thursday's practice with stiffness in his lower back, was back on the field Friday ... Safety Quinton Carter, who is on track to make the roster after two missed seasons with knee troubles, finished his work in a team drill at one point in Friday's practice and jumped on a stationary bike to ride for a few minutes. He then returned to practice ... Wide receiver Emmanuel Sanders reached high for a scoring grab in the back of the end zone in team drills, getting his feet down just before crossing the end line ... Hillman got a few carries with the starting offense in run-game work.
