Eric Young Jr. was forced out of yesterday’s game with pain in his right knee an alarming and unfortunate development for the Mets’ leadoff hitter. Young went 1-for-2 with an infield single in the Mets’ 7-4 win over the Braves before leaving after the third inning. The speedy left fielder hurt his knee Wednesday night when he accidentally spiked Braves starter Tim Hudson on a play at first resulting in a season-ending fracture of the pitcher’s right ankle. Young who has delivered an impressive .356 on-base percentage along with 12 steals in 31 games with the Mets got an X-ray but not an MRI exam. “Just sore” he said. “Playing it safe today.” Terry Collins called it “a knee strain” however which is more than just soreness. Either way it bears watching. Young who was replaced by Andrew Brown thinks it may be possible to play today in Washington. Regarding the Hudson injury Young tweeted yesterday: “For [people] who think I would purposely try [to] hurt someone & felt they needed to say that [to] me ... I will continue [to] pray for [you] as well.” Asked if he received threats on Twitter Young said: “Not necessarily threats just a couple people making malicious comments.” Young said he visited with Hudson and the pitcher’s wife.
