Finnegan posted on his personal Twitter account following his departure from Sunday's Cactus League game against the Mariners that he's "all good" and is only dealing with a "knot" in his left forearm.
This comes as a relief for the Reds, who removed Finnegan from Sunday's start as a precaution after he experienced a lateral spasm in the forearm. Finnegan's next Cactus League could be delayed a bit, but the injury doesn't sound like anything that will jeopardize his bid for a spot in the Reds' Opening Day rotation.
