Just a day after Gordon Hayward's horrific leg injury on opening night, the NBA witnessed probably another serious leg injury. Although not of the same magnitude, Brooklyn Nets' Jeremy Lin looked in serious discomfort, with respect to his right knee, landing awkwardly after a layup attempt:Jeremy Lin was assisted to the locker room after this play. pic.twitter.com/WrdI5jnQNE— Anthony Puccio (@APOOCH) October 19, 2017He can be seen saying "I'm done" multiple times. According to ESPN's Adrian Wojnarowski, there is serious concern regarding the fall:Brooklyn's Jeremy Lin will undergo evaluation of right knee in New York Thursday, league source tells ESPN.

He even took to Twitter to post this message:Gods ALWAYS faithful and in control ????— Jeremy Lin (@JLin7) October 19, 2017While the severity of the injury was yet to be known and announced, a couple of Lin's teammates tweeted prayers and good wishes:Praying for my brother @JLin7 ?? #Undrafted #BrooklynGrit pic.twitter.com/jlwB6G7LhD— Sean Kilpatrick Jr (@SeanKilpatrick) October 19, 2017@JLin7 ??— D'Angelo Russell (@Dloading) October 19, 2017
