Colts DT DeForest Buckner (elbow) is questionable for Sunday's game against the Titans. We'll check his status Sunday morning, but make sure you have another option available for your IDP lineup. S Julian Blackmon (ankle) has been ruled out.

Colts S Khari Willis announced his retirement Wednesday after just 3 years in the league. Willis said he plans "to devote the remainder of my life to the further advancement of the Gospel of Jesus Christ." His retirement leaves an opening in Indy's starting lineup, with Rodney McLeod, rookie Nick Cross and Julian Blackmon looking like the primary competitors. Cross -- a 3rd-round pick out of Maryland -- looks most interesting from an IDP standpoint. He tested great at the Combine -- 98th-percentile 40, 92nd-percentile broad jump, 71st-percentile vertical -- at 6'0, 212 pounds. NFL.com's Lance Zierlein called him "the bouncer of the Maryland defense," lauding his "aggression and explosiveness." Zierlein also highlighted Cross' tackling ability near the line of scrimmage and in the open field, which sounds good for his tackle-collection potential in the pros.

Colts S Julian Blackmon suffered a torn Achilles' tendon in Wednesday's practice and will miss the rest of the season. Indy's 2nd-year starter at FS hasn't been a high-level IDP producer, but the injury takes away a player who as started 22 of the Colts' 23 games since he entered the league. Andrew Sendejo looks like the next man up. Indy lists him as Blackmon's backup on the "unofficial" depth chart, and Sendejo stepped in a couple of weeks ago when S Khari Willis missed time. Sendejo could present some low-level fantasy upside for deep IDP leagues.
