George Kittle and Javon Hargrave have joined Fred Warner in restructuring their contracts to help the San Francisco 49ers free up cap space.

ESPN's Field Yates noted Kittle's restructured deal created $10 million cap space.

Per The Athletic's David Lombardi, the 49ers cleared $6.4 million against the cap by restructuring Hargrave's contract.

The Athletic's Matt Barrows reported on Monday that San Francisco restructured Warner's deal last week.

Per source, the 49ers restructured Fred Warner's contract last week, converting a sizeable portion of his base salary into bonuses. That ought to create some salary-cap cushion as free agency begins in earnest at 9 a.m. today (15 minutes from now).

Lombardi added the 49ers have around $12 million in space against the $255.4 million salary cap right now, with an additional $18 million still to come when their post-June 1 savings from releasing Arik Armstead go into effect.

After their early additions in free agency, the Niners were $6.3 million over the cap before these contract restructures.

Armstead wasn't initially expected to be on the move this offseason, but NFL Network's Ian Rapoport reported the 49ers decided to release him after he declined to take a pay cut.

Designating Armstead as a post-June 1 cut allows the 49ers to spread out his $28.4 million cap hit over the next two seasons.

As a result of all the big-money contracts they have signed in recent years, the Niners have been targeting more secondary players in free agency this offseason. Leonard Floyd has been their biggest addition so far on a two-year, $20 million contract.

There are still areas of the roster that San Francisco seems likely to address. The reigning NFC champs had an agreement in place with linebacker Eric Kendricks before he backed out to sign with the Dallas Cowboys.

Dre Greenlaw's recovery from a torn Achilles suffered in the Super Bowl means the 49ers could still use another starting-caliber linebacker. They also have needs at cornerback and safety, particularly with Talanoa Hufanga coming off a torn ACL.

Some of those positions will likely be addressed during the draft, but there are also good players still available in free agency who could be of interest to San Francisco.

Freeing up money by restructuring the deals for Kittle and Hargrave gives the front office leeway to potentially make one or two more key signings.

If not, the 49ers could also look to keep some of their cap space clear for this season with the intention of rolling it over into 2025.
