Here is how Mets catcher Travis d'Arnaud, cleared to resume baseball activities Thursday, went about recovering from the concussion he suffered May 13 when he was struck in the head by Alfonso Soriano's backswing:

"I just laid in bed,'' he said, "and sometimes if I was bored of that, I'd go to the couch and lay on the couch. That was pretty much it.''

His symptoms worsened shortly after the initial blow, d'Arnaud said, with a "slight headache, being really sensitive to light and sound, trouble sleeping at night.''

It was his third baseball concussion after a May 2011 incident in which he took two foul balls to the head and a 2008 play at the plate, he said. "My mask was off,'' he said, "and I took a foot to the face.''

D'Arnaud said he began to "feel great'' on Tuesday and threw, ran and worked in the indoor batting cage Thursday. "If things pan out,'' Terry Collins said, "he's going to hit on the field [Friday].''

There is no target date for his return.

Gee on the way backDillon Gee (strained back muscle) threw on flat ground Thursday and hopes to work out on a mound Friday. He could have a rehabilitation pitching assignment in Binghamton, or for St. Lucie at Palm Beach, on Sunday or Monday and miss only three turns in the rotation.

Dodgers release OlivoThe Dodgers announced the release of Triple-A catcher Miguel Olivo two days after he fought teammate Alex Guerrero in Albuquerque's dugout and bit off a piece of his ear. Guerrero underwent plastic surgery and could miss more than a month. Olivo, 35, hit .217 in eight games for the Dodgers this year. He was hitting .368 for Albuquerque, second on the team to Guerrero's .376.
