SANTA CLARA — As part of their post-concussion protocol, tight end Vernon Davis and safety Eric Reid went through light-impact tests Friday, and they did so by facing off against each other.
The 49ers list both players as questionable for Sunday's game at New Orleans, and neither has suffered any setbacks since exiting with a concussion in last Sunday's 10-9 loss to the Carolina Panthers.
Coach Jim Harbaugh said it seems both players are on track to play against the Saints, though they'll need to stay asymptomatic until kickoff.
After practice Friday — and before the 49ers headed to the airport — Davis initially opposed rookie cornerback Darryl Morris in the contact drill before facing Reid. The players lined up a few yards apart and basically extended arms into their chests and shoulders, with no contact involving their helmets.
“We obviously weren't trying to kill each other,” Reid said, “but we got the point of the drill accomplished.”
Reid, who's started every game his rookie season, said it's the same protocol he followed after a Sept. 15 concussion at Seattle. He didn't have any sensitivity to light after Sunday's injury, allowing him to study film as he does on normal weeks.
Davis said of opposing Reid: “We just had to get banged around a bit. It just depends now on how we feel the next two days. He was a pretty physical guy.”
Davis is the 49ers' second-leading receiver, and he has a team-high seven touchdown receptions. Anquan Boldin, the team's leading receiver, accounts for the 49ers' only other two touchdown catches.
Coincidentally, the only two players ruled out by the Saints are victims of concussions, those to safety Kenny Vaccaro and tight end Benjamin Watson.
MORE INJURY UPDATES
Defensive tackle Ray McDonald (left ankle) was ruled out, and he'll be replaced by the platoon of Tony Jerod-Eddie and Demarcus Dobbs, Harbaugh said.
