Maybe Alison Sweeney should host The Tonight Show. Lord knows she already works on every other show at NBC.

The next phase of the Days of Our Lives and Biggest Loser star’s quest for complete Peacock domination kicks in this March, when she guests on the network’s freshman medical drama, Mercy.

According to sources, Sweeney will play a bus-crash victim who appears to have only minor injuries. However, the docs and nurses soon discover (spoiler alert!) that she has shrapnel in her brain, causing her to act out of character.
