Sam Martin's bid to make the Pro Bowl this fall is off to a rough start.

Martin, who set a franchise record for net punting average in 2016, will miss part of training camp with an ankle injury he suffered earlier this month, the Detroit Lions announced today.

The Lions placed Martin, a Pro Bowl alternate last year, offensive tackle Cyrus Kouandjio and rookie cornerback Teez Tabor on the active/non-football injury list, and placed left tackle Taylor Decker and five others on the active/physically unable to perform list.

Martin's injury came as a bit of a surprise one day after Lions rookies, quarterbacks and injured players reported for work. The full team reports on Saturday, and the Lions will hold their first practice of training camp Sunday.

Kasey Redfern, who signed as a free agent in April, will handle punting duties during Martin's absence.

Kouandjio still is recovering from off-season hip surgery he had when he was still a member of the Buffalo Bills, and Tabor said earlier this spring he wasn't completely over the hamstring injury he suffered during pre-draft workouts.

Decker, meanwhile, underwent shoulder surgery in June and is expected to miss at least the first half of the season.

If a player opens the regular season on the PUP list, he isn't eligible to return until Week 7, which coincides with the Lions' bye week this year.

With Decker out, the Lions are expected to have an open competition for the left tackle job. Greg Robinson, acquired in a June trade with Los Angeles Rams, Kouandjio, Cornelius Lucas and Corey Robinson all are candidates to play the position this year, though Corey Robinson joins Decker on the PUP list as he continues his recovery from off-season foot surgery.

Along with Decker and Robinson, the Lions also placed defensive ends Armonty Bryant and Jeremiah Valoaga and safeties Don Carey and Rolan Milligan on the PUP list today.

Bryant (knee), Valoaga and Carey (knee) all missed significant time this spring with injuries. Bryant also will serve a four-game suspension for violating the NFL's policy on substances of abuse to start the season.

Three other projected starters who missed time with injury this spring have been cleared to practice on Sunday, though it remains to be seen how carefully the Lions will manage their reps.

Right guard T.J. Lang avoided the PUP list after undergoing January hip surgery, Theo Riddick's surgically-repaired wrists have been deemed structurally sound, and linebacker Tahir Whitehead is good to go after sitting out minicamp and organized team activities while recovering from a knee injury.
