Eyebrows were raised all over Central Indiana on Friday when the Indianapolis Colts practice report listed quarterback Peyton Manning as a “limited participant” with the qualifier: “not injury related — rested.”

Get used to it.

“It’s something we talked about before the season, in November, kind of easing back on Fridays a little bit from a rep standpoint; just try to be rested from an arm standpoint,” Manning said after the Colts beat San Francisco 18-14 on Sunday.

“I participated in the part of practice that I needed to, but I did take some rest, which is what we talked about starting in November.”

On the subject of injuries, Colts coach Jim Caldwell said Monday that he could provide no prognoses on cornerback Kelvin Hayden (knee), linebacker Tyjuan Hagler (elbow) or running back Donald Brown (shoulder). Hayden and Hagler were unable to finish the game Sunday; Brown was unable to play.

Of the possibility of wide receiver Anthony Gonzalez (knee) returning to practice this week, Caldwell said that is up to the team doctors and how Gonzalez feels. He has missed the past six games.

First sacks ‘well-deserved’

Late-game, drive-killing sacks by Colts defensive ends Robert Mathis and Dwight Freeney , crucial as they were, were not unexpected. But a couple of lower-profile teammates also got a chunk of the action Sunday.

Reserve linebacker Philip Wheeler and defensive tackle Antonio Johnson got their first NFL sacks.

Wheeler, playing in place of Hagler, ran San Francisco quarterback Alex Smith out of bounds for no gain, which is scored a sack. Johnson was in the right place at the right time: When Smith tripped, Johnson was the first man to him.

Johnson plays a thankless position where the double-teams are almost constant and the highlights are few. He offered no apology for his good fortune.

“I think it was well-deserved,” he said with a laugh. “I was there first. We’ll take them however they come. It’s in the books now.”

Freeney’s eighth sack moved him into a share of third place on the league list.

He couldn’t be blamed for envying the leader, Minnesota’s Jared Allen . Of Allen’s 101/2 sacks, 71/2 have come in two meetings with Green Bay’s Aaron Rodgers , the most sacked quarterback in the league (31).

A Silva streak

With punt returner T.J. Rushing inactive because of roster priorities, Jamie Silva handled those duties Sunday. He averaged a middling 5.3 yards on six returns with one fumble, which he recovered.

On punt and kick coverage, he was a terror.

“The guy makes a lot of plays. He’s all over the field,” Caldwell said. “He’s a force to be reckoned with every time that ball is snapped on any of our kicking teams and he gives us great effort as well.”

Silva made five special teams tackles, including one at the San Francisco 12 on a kickoff.

Etc.

Through Sunday’s games, Colts WR Reggie Wayne was second in the NFL in receptions with 51 and receiving yards with 689, and tied for second in receiving touchdowns with six. He caught 12 passes for 147 yards and the winning touchdown Sunday. . . . The Colts played without a turnover for the second consecutive game and third time this season. They are plus-6 in giveaway-takeaway differential and have outscored opponents 44-9 off turnovers.
