The Detroit Lions will sign Anquan Boldin to a one-year deal.

Boldin and the Lions, who need depth at receiver in the wake of Calvin Johnson's retirement, were finalizing the deal Tuesday.

Detroit had brought Boldin in for a workout last month but did not sign him at the time. 

Boldin, who will turn 36 in October, has been to the Pro Bowl three times.

Arian Foster is scheduled to work out for the Miami Dolphins and Detroit Lions this week.

The running back will audition for the Dolphins on Monday and Lions a few days later.

Foster tore an Achilles in Week 4 last season, and hasn't played all 16 games since 2012.

Jahvid Best will become the first former NFL player to participate in the Summer Olympic Games after being approved to represent St. Lucia in track and field next month in Rio.

The former Detroit Lions running back will run in the 100 meters for St. Lucia. Best was born in Vallejo, California, but his father holds dual citizenship in St. Lucia and the United States.

"This is a huge accomplishment for me, but at the same time this is just the beginning," Best, 27, told NBC Sports. "I have only been in this sport for two years professionally, and plan on being around for a long time."
