Colts GM Ryan Grigson is keeping his options open at center, writes Mike Wells of ESPN.com. The Colts released last season’s starting center, Samson Satele, in March and Phil Costa suddenly retired last month, leaving Khaled Holmes, the likely starter, and Thomas Austin as the centers on the roster. Guard Donald Thomas, who was signed a year ago, can also play some center but has question marks after suffering a torn tendon in his quad and a torn bicep last season.

Here are a few more Friday evening items from around the AFC:

• The Raiders haven’t had a 1,000-yard receiver in eight seasons, so it only makes sense for Scott Bair of CSNBayArea.com to run down the most intriguing wide receiver options for the club in the upcoming draft. The list starts with (who else?) Sammy Watkins, but also highlights Mississippi’s Donte Moncrief, Penn State’s Allen Robinson, Indiana’s Cody Latimer, Florida State’s Kelvin Benjamin, and Fresno State’s Davante Adams as solid options outside of the first round.
• Count the Chiefs as a sleeper team to potentially draft a quarterback in the first three rounds next week, tweets Chris Mortensen of ESPN.com. Of course, unless Kansas City makes a trade, the club won’t have a second-round pick.
• Terez A. Paylor of the Kansas City Star (on Twitter) gets the sense that the Chiefs will focus on offensive lineman, cornerbacks, wide receivers, and outside linebackers in the first round. However, studs who fall at other positions like tight end and – as Mortensen suggests – quarterback could be in play.
• Aaron Wilson of the National Football Post reports that Nebraska wide receiver Quincy Enunwa visited the Raiders and Steelers, and also writes that Stony Brook wideout Malcolm Eugene worked out for the Raiders, Colts, and Jets.
