Arizona Cardinals center Rodney Hudson didn’t appear Tuesday for the first day of the team’s mandatory training camp.
Cardinals coach Kliff Kingsbury termed Hudson’s absence as “unexcused.”
Kingsbury declined to divulge details but said, “We’re working through something with him.”
Hudson, who turns 33 in July, wasn’t attending the team’s voluntary Organized Team Activities leading up to minicamp.
Hudson was acquired by the Cardinals from the Las Vegas Raiders prior to last season.
He signed a three-year, $30 million extension with $16 million guaranteed just 14 months ago.
Hudson is slated to earn $10.85 million in base salary this season.
A three-time Pro Bowler with the Raiders, Hudson has played in 155 games (139 starts) over 11 seasons with the Kansas City Chiefs (2011-14), Raiders (2015-20) and Cardinals.
