The Panthers are expected to place Marshall on injured reserve Wednesday with an unspecified injury, David Newton of ESPN.com reports.
Once the transaction is completed, Marshall won't be eligible to play in Sunday's season finale in Tampa Bay. Marshall's rookie season is thus on the cusp of coming to an end, with the second-round selection having struggled to justify the hype he generated coming out of training camp and the preseason. Through 13 appearances, Marshall secured only 17 of 30 targets for 138 yards. He has yet to score his first NFL touchdown.
