Scala: returning results from a case match

I am attempting to write a helper class for querying my database. It looks something like this:

object Injury {
  def logger =  LoggerFactory.getLogger(getClass)

    def find(teamId: Int = 0) {
        logger.info("teamId in find(): " + teamId)
        teamId match {
            case 0 => findAll
            case n => findById(n)
        }
    }

  def findAll = {
    val results = InjuryDAO.findAll
    results.map(grater[Injury].asObject(_)).toList
  }

  def findById(teamId: Int) = {
    //
  }

}

Now in my controller, I can simply call Injury.find(someId) and field the correct results. The problem is I'm not seeing any results, so I believe my Scala logic is incorrect somewhere. If I call Injury.findAll directly from my controller, all works great. in this case I'm passing a 0, verified it with the logger, but the case 0 which should invoke findAll isn't being triggered properly. Obvious error here?

def find(teamId: Int = 0) {

= is missing, explaining why your method doesn't return anything (Unit).

Should be:

def find(teamId: Int = 0) = {
