Colon was activated from the reserve/COVID-19 list Friday, Cliffton Brown of the Ravens' official site reports.
Colon's return will boost the Ravens' offensive line depth, which is currently depleted. It's possible he could get significant work at center Sunday against the Bengals if Bradley Bozeman has to shift to guard with Ben Powers (foot) out, Tyre Phillips (knee) doubtful and Patrick Mekari (hand) questionable.
