Free agent wideout D.J. Hackett agreed to two-year, $3.5 million deal with Carolina on Monday as the Panthers continued to upgrade their receiving corps.

The former Seahawk chose Carolina over Seattle, Washington and Tampa Bay, according to his agent, Kevin Robinson.

The Panthers have been busy trying to get star receiver Steve Smith help after he faced constant double-teams last season. The Panthers signed receiver Muhsin Muhammad last month after he was released by Chicago.
