Is this wrongful termination settlement income taxable

My husband was terminated wrongfully from the US Postal Service after he was physically injured on the job.  He filed a lawsuit and won.  He received two settlement checks.  One that was for actual back payment income which was taxed and reported on a W-2.  The 2nd payment had no taxes taken out, and was reported on a 1099-MISC.  My question is, is this 2nd payment taxable?  Do I need to claim it as income on our tax return this year?  I was reading the rules on the IRS website and it sounds like if the damages paid were the result of a personal physical injuries (which they were) they can be excluded from being claimed.  I want to make sure I am reading that correctly.  My husband's attorney seems to believe this as well.
