Adam Humphries was an undrafted free agent from Clemson who caught the Bucs eye in a rookie tryout camp in 2015. Last season, he was second on the team in receptions with 61 for 631 yards and one touchdown.That earned Humphries a substantial raise on Monday. The Bucs placed a second-year tender of $2.914 million for 2018 on Humphries as a restricted free agent. He made $615,000 in base salary last season.That means the Bucs will have the right of first refusal of any potential offer sheet Humphries may sign with another team. If they decided not to match, they would receive a second-round pick as compensation.The Bucs also kept key depth at linebacker by re-signing Glanton to a one-year contract. Glanton, 27, had been non-tendered as a restricted free agent — which would've meant one year at $1.9 million — but instead gave him a $250,000 signing bonus to go with a $790,000 base salary for 2018. Glanton, who had 20 tackles in a three-game span at linebacker, suffered a broken leg in the season finale against New Orleans but should be fully recovered next month.
