Brinkley, who sat out the entire 2011 season after suffering a preseason hip injury, returned to practice for the first couple weeks of OTAs, but after getting tangled up with another player while breaking up a pass two weeks ago, the final week of OTAs was spent watching with a groin injury.
On Tuesday, Brinkley remained on the sidelines, only this time he said it was an issue his hip, not the groin.
"Just a process with the hip, still keep going so hopefully I'll be out at practice one day before (minicamp is over)," Brinkley said.
"This goes back to the hip. Other than that, though, everything is good."
Brinkley is being counted on as the Vikings' new starting middle linebacker after the team decided not to re-sign nine-year veteran E.J. Henderson, who remains a free agent. Brinkley started the final four games of the regular season and two playoff games for the Vikings in 2009 after Henderson fractured his femur.
His experience there and getting in some work in the earlier OTAs has Brinkley feeling like the coaches know what he can do, even if he isn't on the field during minicamp.
"The first couple of OTAs, I was able to do a little bit. I was able to show what I could do," Brinkley said. "I'm pretty sure if the coaches weren't satisfied they would bring somebody else in. It's still a work in progress."
Brinkley called his absence on the field "precautionary" and said it definitely wouldn't have kept him sidelined if it were the regular season.
The play of the day was a bullet from Christian Ponder to tight end John Carlson, a pass that was threaded between two linebackers who were left on the ground while Carlson ran into the end zone and dunked the ball over the goalposts.
But it wasn't all gravy for Ponder and the quarterbacks. Whether it was a miscommunication on the route or just a poorly thrown pass, Ponder had an off-target pass intended for Jerome Simpson intercepted by Antoine Winfield while backup Joe Webb had a weak, wobbly pass over the middle of the field intercepted by safety Andrew Sendejo.
Ponder and Webb each took at least one touch sack during full-team drills, as well.
Backup defensive end D'Aundre Reed got to Webb and Nick Reed got to Ponder.
