The Jaguars on Thursday made progress toward getting three more rookies to camp on time by signing third-round cornerback Derek Cox, seventh-round receiver Tiquan Underwood and agreeing to terms with their other third-round pick, defensive tackle Terrance Knighton.

With two days remaining before players report to training camp, the Jags still need to sign their top two picks, tackles Eugene Monroe and Eben Britton.

The contracts for Cox, Underwood and Knighton include minimum salaries of $310,000, $385,000, $480,000 and $565,000, plus an escalator to $1.3 million in the fourth year that increases the maximum value of the deals. The escalator compensates the players, who signed four-year contracts, for not being eligible to become restricted free agents after their third season.

Knighton’s contract, which he’ll sign on Sunday, includes an $843,500 signing bonus. Cox and Underwood receive bonuses of $833,000 and $36,500, respectively.  

The Jaguars also appear to be close to signing Britton.  The two sides are still negotiating the signing bonus, but a deal could be done as early as today.
