It doesn't look like Whalen is going to be ready for Week 1 against the Rams. Gehlken added Whalen could be a candidate for injury settlement. The Raiders just traded Ryan Switzer to the Steelers and Whalen was among those battling for the slot receiver job.
Hillman, a former San Diego State Aztec, was released by the Vikings this week after playing in five games for them. The Chargers released WR Griff Whalen in a corresponding move.
Hillman has been in the league for five years (debuted in 2012), and crazy enough is still only 25 years old.
The Chargers don't have much depth behind Melvin Gordon who has seen a big workload this year but especially the last few weeks. The team talked about getting Kenneth Farrow more work but it hasn't happened. Hillman struggled in Minnesota but could provide the Chargers some depth at the position, and they should be pretty familiar with Hillman seeing him twice a year the last couple of seasons.
