— With Castonzo back in the fold at left tackle Wednesday, we saw a continuance of last week's first-team offensive line at every other position: Quenton Nelson at left guard, Ryan Kelly at center, Matt Slauson at right guard and Austin Howard at right tackle. Denzelle Good, who filled in for Castonzo at left tackle last week, also was seen working in with the first team at times on Wednesday, too.

— A second unit working along the offensive line included Good at left tackle, Mewhort at left guard, Joe Haeg at center, Braden Smith at right guard and Jared Machorro at right tackle.

— Staying with the big fellas, only on defense, the Colts showed a base first-team defensive line look that included Jabaal Sheard and Tarell Basham at defensive end and Al Woods (one-technique) and Denico Autry (three-technique) at defensive tackle. But, again, just like last Wednesday's practice, lots of other players were seen filling in up front, like fourth-year veteran Rakeem Nunez-Roches, who appeared to be spelling Woods at the one-tech spot. Margus Hunt (defensive tackle) and John Simon (defensive end) were also rotating in and out.

— It appeared the three base linebackers stayed the same from last week, too: Najee Goode at the WILL, Anthony Walker at the MIKE and Antonio Morrison at the SAM. Tyrell Adams also had plenty of reps at linebacker.

— Geathers and Hooker being out continued to open the door for others to step in on Wednesday at the safety position, including T.J. Green and Ronald Martin. Pierre Desir, Kenny Moore II, Nate Hairston and Quincy Wilson were the primary cornerbacks seen rotating in and out.

— With Mack out, the running back position is certainly fluid. It was veteran Robert Turbin getting early snaps with the top unit on Wednesday, but Nyheim Hines (who was all over the field again, like last week), Christine Michael and Josh Ferguson were also getting plenty of reps with the ones, too. Jordan Wilkins got a few snaps here and there, as well.
