Which receiver do i add?

i just traded Jamal Lewis and Ronald curry for Andre Johnson. that gives me Steve smith, tj housh, and Andre Johnson at wr. Johnson is hurt right now and i have an extra spot to fill. i have no other healthy receivers so i need to add one which one do i add? santonio Holmes, kevin Curtis, Shaun McDonald, Calvin johnson, or roddy white. or maybe u give me somebody else that i could check on. also andre davis is a free agent and he is going to start against the pathetic atlanta deffense so i can grab him for a one week performance
