Indianapolis linebacker Bjoern Werner will miss four to six weeks with a sprained right foot. Werner was the Colts' first-round pick in April's draft.
Coach Chuck Pagano said Monday that Werner tore the plantar fascia during Sunday's 37-3 victory at Jacksonville.
Fullback Stanley Havili also is expected to miss this week's game with a sprained ankle.
Pagano said he expects starting center Samson Satele to return to against Seattle this weekend after missing the last two games. Pagano couldn't say whether safety LaRon Landry or running back Ahmad Bradshaw would play this week.
Indy (3-1) also will get receiver LaVon Brazill back on the practice field after completing his four-game suspension for a violation of the league's substance abuse policy.
The Colts have a one-week exemption on activating Brazill.
